Solution
The GDDR5 is going to perform better in any scenario. The speed of the ram matters more than the amount since card at that performance level will run out of processing power before memory.
The extra memory is useful for (very) high resolution textures and screen resolutions but the HD6670 lacks the processing power to drive high resolutions so 2GB DDR3 is ultimately useless. Going with GDDR5 makes more sense.

Then again, the HD6670 is barely on par with modern IGPs so you might want to aim higher than that.
